Dressing substrate
A wound shield to manage repetitive access stress may include a conformable substrate to circumscribe a wound. Any suitable dressing may be secured to the conformable substrate providing separation between the wound and the dressing. The wound substrate may provide a site for attachment of adhesive dressings to shield the patient's skin from the pain of repetitive access and or removal of the dressings. A conformable substrate may be composed of one or more layers of any suitable material and may include adhesive on one or more surfaces to secure the substrate to the wound site and or to secure the dressing to the conformable substrate. A wound substrate may include strong adhesive to secure the substrate to the patients skin. The conformable wound substrate will be formed of any suitable non-absorbent material to permit long term application adjacent a wound. Thus many dressings may be applied and removed from a single wound substrate shielding the patient's skin from repetitive insult. A wound substrate according to the present disclosure may also be combined with a conformable frame to provide exudate management and or pressure distribution around a wound.
1. A wound care apparatus comprising:
a conformable wound substrate configured to circumscribe a wound;
a layer of adhesive configured to be disposed between the substrate and a patient's skin to adhere the substrate to the skin;
an elongated conformable frame configured to be wrapped around the wound in an overlapping, spiral fashion to thereby define a wound space adjacent the wound;
a cover engaging the conformable frame and configured to enclose the wound space; and
an additional layer of adhesive disposed on a lower surface of the elongated conformable frame.
2. The wound care apparatus of claim 1 wherein the conformable frame comprises an exudate absorbing material.
3. The wound care apparatus of claim 2 , wherein the substrate comprises a non-absorbent material.
4. The wound care apparatus of claim 1 , wherein the cover comprises a medium for exudate storage.
5. The wound care apparatus of claim 1 , wherein the conformable substrate comprises an elongated strip wrapped around the wound in a spiral.
6. The wound care apparatus of claim 1 , wherein the elongated conformable frame comprises a strip of polyurethane foam.
7. The wound care apparatus of claim 1 , wherein the elongated conformable frame has a length and a height, wherein the height is uniform along the length.
8. The wound care apparatus of claim 1 , wherein the elongated conformable frame has a length and a height, wherein the height varies gradually and continually along the length.
9. The wound care apparatus of claim 1 , wherein the elongated conformable frame includes a non-absorbent material and an absorbent material.
10. The wound care apparatus of claim 1 , wherein the substrate has a width and a height, wherein the width is from 10 to 100 times the height.
11. The wound care apparatus of claim 1 , wherein the additional layer of adhesive is disposed between the substrate and the elongated conformable frame and adheres the substrate to the elongated conformable frame.
12. The wound care apparatus of claim 1 , wherein the elongated conformable frame is removable relative to the substrate.
13. The wound care apparatus of claim 1 , wherein the elongated conformable frame transfers exudate from the wound to the cover.
